 I trust that the following additional particulars, thus obtained, 

 will not bo considered uninteresting or out of place in tho 

 Society's Journal. 



Mr. Couch, in his paper, stated the length of the species to be 

 an inch and five-eighths. This I believe to be about their usual 

 or full size, as I have never yet met witli them larger, but have 

 seen some much smaller, as will be hereafter specified.

 Depth of head, behind the eye, two-eighths of an inch, which
